yeah pretty good although it is random how he gets infectedwhen he opens the jar and that he attacks his other exploreralso why does he get turned so quickly when jeff was taking along time to change

pfff, you seriously dont get it? its because Jeff drank a Vitamin Water before he went to find the treasure, hence causing him to change slower as the vitamins and antioxidants in the drink helped his immune system.

jeff took a while to infect because there was only a small amount of active Blank nearby. It had to reproduce to become a greater mass. however, there was already a large mass of Blank nearby the gray guy, so it didn't have to take the time to reproduce itself.
